Flathead fact wanted ! HELP!

Hello all, can any one tell me the torque spec for ALUMINUM heads for 80" flathead? Shop Dope say`s "snug and secure", I`m hoping for a more definite answer! T.I.A.

Tight is tight and too tight is broken? Using a genuing H.-D. head bolt wrench tighten the bolt till the wrench flexes an inch? These are what old time factory trained mechanics have told me.
